BaseScore

BaseScore is an open-source, unofficial Base activity score and airdrop rank simulator.

Paste a Base wallet address or ENS name, get a clean 18-point activity score, review the wallet footprint, compare another wallet, and share the result on X.

100% unofficial and speculative. Base has no confirmed token, points program, or airdrop. DYOR. Not financial advice. Not affiliated with Base, Coinbase, or any listed protocol.

• 52-week GitHub-style activity heatmap.
• Protocol fingerprint for known Base apps.
• Sybil risk meter with transparent signals.
• FDV and airdrop allocation simulator.
• Compare mode for a second wallet.
• Save up to 5 named wallets in browser localStorage.
• Static high-activity leaderboard preview.
• Share on X button.
• Dynamic OG image route.
• PWA manifest.
• No database, no auth, no wallet connection.

Why This Checker Wins

• It explains the score instead of hiding the model.
• It never asks users to connect or sign.
• It is fast because analysis is capped and cached.
• It is transparent about unofficial, speculative scoring.
• It is designed for mobile sharing and clean social previews.
• It can later scale with a KV cache without rewriting the app.

Data Sources

The default deployment uses only free public sources:

• Blockscout Base API for wallet activity: https://base.blockscout.com/api
• Base public RPC only as a balance fallback: https://mainnet.base.org
• Ethereum public RPC only for ENS resolution: https://eth.llamarpc.com

Free public APIs can rate-limit under traffic spikes. BaseScore reduces risk by using request caps, in-memory caching, CDN cache headers, partial scoring, and clear fallback messages.

Scoring Model

BaseScore gives 1 point for each signal:

1. Holds ETH on Base.
2. Meaningful Base ETH balance.
3. At least 10 Base transactions.
4. At least 50 Base transactions.
5. Active on at least 7 unique days.
6. Active across at least 4 unique weeks.
7. Active across at least 3 unique months.
8. First Base transaction older than 90 days.
9. Bridge-like activity detected.
10. Meaningful native value moved.
11. Meaningful gas spent.
12. Interacted with at least 10 unique contracts.
13. Touched at least 3 known Base protocols.
14. DEX interaction detected.
15. Lending or DeFi interaction detected.
16. Token or stablecoin activity detected.
17. NFT or creator activity detected.
18. Low sybil-risk activity pattern.

Tier mapping:

16-18 Mythic
13-15 Gold
9-12 Silver
5-8 Uncommon
1-4 Eligible
0 No Signal

Optional Future Scaling

For 1,000 users, the default no-database version is enough if traffic is moderate.

If the app goes viral, add a free or low-cost KV cache such as Upstash Redis for:

• Global wallet result cache.
• Real leaderboard storage.
• IP rate limiting.
• Longer cache TTLs.

The code is structured so this can be added in lib/cache.ts without rebuilding the UI.

Security And Privacy

• No wallet connection.
• No signatures.
• No auth.
• No database.
• Saved wallets stay in browser localStorage.
• Analysis uses public blockchain data only.

Contributing

PRs are welcome for:

• More known Base protocol addresses.
